Elasticsearch url is redirecting after installing X-Pack

[mruthyu (MJay)]

After installing X-Pack http://elasticserver:9200/ prompts for Basic authentication and after providing elastic/changeme as username and password again it prompts for the credentials.

Elasticsearch version: 5.4.3
X-Pack version : 5.4.3

When I use x-pack API to get the users list I see the following error. How to start native user service?

{"error":{"root_cause":[{"type":"illegal_state_exception","reason":"users cannot be retrieved as native user service has not been started"}],"type":"illegal_state_exception","reason":"users cannot be retrieved as native user service has not been started"},"status":500}
